tRPC is a TypeScript framework for building end-to-end typesafe APIs without code generation or schemas. It leverages TypeScript's type inference to provide full static typesafety and autocompletion between client and server, with zero runtime dependencies. tRPC v11 supports queries, mutations, and subscriptions via HTTP GET/POST and WebSocket adapters for Express, Fastify, Next.js, AWS Lambda, and edge runtimes.
